| Abstract: | The resilient S-boxes have applications in fault tolerant distributed computing,quantum cryptographic key distribution and random sequence generation for stream ciphers.Based on the use of linear error correcting codes together with highly nonlinear S-Boxes,a new construction of highly nonlinear resilient S-boxes with given degree is provided.A contribution of the construction is that the nonlinearity of the resilient S-boxes can be calculated with the parameter of the linear code.As a result,the constructi... |
